Oiler



Patented July 2, 1940 A UNITED STATES garan-T' ori-fica 3 Claims.

My invention relates to improvements in oilers r oil cans and the main object is to provide a device embodying a container orcan for the oil,

\ a spout and means for compressing airin the iid" container to eject the oil forcibly from the container through the spout and allow the convenient and safe oiling of machinery without elen vating the can over the part being oiled.

Another `object `is to provide a device of this kind in a simple and convenient form comprising an oil can,` an air pump connected tothe can, a handle adjacent the pump,` a spout having a ball and socket connection to the can, a valve controlling the flow of oil to the spout, and a thumb lever adjacent the handle controlling the said valve.

A further object is to provide a novel pump and handle assembly for an oiler `of this kind in which the plunger actuating arm of the pump y forth and claimed, reference being had to the i accompanying' drawing wherein:

Figure 1 is a side elevation, partly in section,

` of my oiler.

Figure 2 is a section along the line 2 2 in Figure 1.

Figure 3 is an enlarged sectional detail view of the ball and socket.

Figure 4 is an enlarged section along the line 4 4 in Figure 1.

Figure 5 is an enlarged section along the line 5 5 in Figure 1.

Referring now with more particularity to the drawing my invention comprises an oil can or container 6 of any desired size and material having the wall `I, bottom 8 and top 9, the latter having a cap `Ill which when removed permits the filling of the can with oil. The can 6 is not circular in plan` or cross section but as shown in Figure 2 is of ovoidal shape having the large round back portion II and relatively sharp front portion I2.

A handle I3 is secured by rivets or other suitable means at I4 to the upper back portion of the can and from that point is bent outward and then downward forming a leg I5 extended parallel and spaced outwardly or rearwardly from the can. This handle I3 is formed up from a strip of metal the edges I6 of which are turned (ci. zeisgi inwardlyfor` stiffening and to provide channels or guides I'I.

Anf air pump I8 including the bottom cap or head i9 and upper cap ZI) is mounted alongside the back of the can byA a threaded nipple 2l 5 on the cap I3 which is screwed at 22 into the can. A channel 23 connects the nipple with the pump cylinder 24 and a conventional ball check valve 25 is provided inthe channel opening toward the inlet of the channel into the can. The

' pump plunger or piston 26 is slidably mounted in the cylinder 24 and has itsv operating rod 21 extended slidably up through the cap 2l). An expansion coil spring 2v8is coiled around the rod 2'! and braced between the cap 2l]` and the plunger 15 26 normally urges the same downwardly as shown. An operating` arm 29 is secured to the upper exposed end of the operating `rod 21 by nuts 33 and extends outwardly or rearwardly to the leg I5 of the handle I3. Like this handle the arm 29 is formed up from strip metal folded inward at its edges but these folds are out away at 3l toward theiouter end of the arm to provide a guide ear 32 which `is adapted to enter between the folded edges I6 of the handle leg 25' I5 and is upset to form projections or teats 33 which ride the channels I1 in the said leg. Thus the leg I5 of the handle acts as a guide for the arm 29 while the two mutually support each other to form a rigid assembly. Of course, the

arm 29 normally stands some distance down on the leg I5 so that by raising the arm with the fingers of the hand holding the handle the plunger 23 may vhe raised in the cylinder 24 and then when released the spring 28 pushes the 35 plunger down forcing air, which is drawn in at 34, dliown through the check valve 25` into the can A valve housing or T 35 is mounted in the top 9 near the frontal portion thereof, the said 40 housing having a threaded center extension 36 threaded at `3l in the top for this mounting. A pick up tube 38 extends from the extension 36 down into the can 6 to a point near the bottom 8 and this tube is bent forwardly slightly at 39 45 so that its lower end will rest close into the corner formed by the junction of the sharp front I2 of the can and the bottom. By this arrangement the oil may all be drained from the can by slightly tipping the can forwardly as will `be understood.

The tube 38 communicates with a central bore lill in the barrel 4I of the housing'35. This bore is enlarged at its frontal end 42 and a hard rubber bearing 43 is placed in this enlargement and has 55 an aperture 44 communicating with the bore 40. The outer face of this bearing has a rounded or hemisphered recess 45 and the rounded or ball shaped end 46 of the spout 41 is placed in this recess. A cap 48 is screwed on the end of the barrel 4I and has a central aperture 49 beveled off to t the ball 46 and hold the same in place against the bearing 43. The bore 59 of the spout 41 is widened Where it opens through the ball 46 so that in any angular position of the spout the bore 50 will communicate with the bore 40. The other or rear end of this bore 40 is also enlarged and a `plug 5| is screwed at 52 in this enlarged end. A valve stem 53 is slidably mounted through the plug 5| and has a valve head 54 at its end engaging the end of the bore 40 under influence of an expansion coil spring 55 braced between the valve head and plug.

A thumb lever 56 is fulcrumed at 51 in a bracket 58 secured to the top 9, the rear end of the lever being turned down alongside the handle i3 in position to be conveniently operated by the thumb of the hand holding this handle. A link 59 then pivotally connects the other end of the lever 56 and the exposed end of the valve stem 53.

In use the can 6 is i'llled with oil by removing theycap Il) and then the cap is closed tightly and the can grasped by the handle I3. The fingers are then used to raise the arm 29 several times and as it is released the plunger 26 forces air into the can as described. When the pressure in the can is sufficient the thumb lever 56 is depressed pulling on the valve stem 53 and unseating the valve head 54 allowing the oil to flow out through the spout 41 under the inuence of the air pressure in the can. 'Iyhus it is evidently unnecessary to raise or otherwise manipulate the can itself tooil any machine part.

The spout 41 may be swung to any angle desired and for this purpose a finger yoke 60 is secured A to the spout adjacent its ball end 46, the said yoke having the hooked or arcuate wings 6l by which the stem may be readily manipulated.

While I have herein set forth a certain preferred embodiment of my invention, it is understood that I may vary from the same in minor structural details, so as best to construct a practical device for the purpose intended, not departing from the spirit of the invention and within the scope of the appended claims.

I claim:

In an oiler, a container, an open handle on the container having a leg extended downwardly substantially parallel with the adjacent container wall, a cylindrical air pump on the container wall in ,parallelism with the said leg and communieating at its lower end with the container, a spring-set piston and rod in the pump cylinder and adapted on its downward movement to force air into the container, a check valve to hold the air in the container, the piston rod extending slidably up through the upper endof the cylinder, a piston operating arm secured at one end to the upper end of the piston rod, the opposite end of this arm being slidably associated with the said handle leg, and a valve controlled oil delivery spout communicating with the container and through which oil may be forced from the container by compressed air therein.

2. In an oiler embodyinga container and an oil delivery spout communicating with same and through which oil may be forced by compressed air, a handle at one side of the container, vincluding a leg extended in axial spaced relation to the adjacent wall of the container, a cylindrical air-pump on the container wall disposed parallel to the handle leg and having a valve controlled air-inlet into the base of the container, a spring-set piston and rod in the cylinder, adapted on its downward movement to force air into the container through said Valve controlled inlet, the rod extending slidably up through the upper end of the cylinder, a piston operating arm secured at one end to the upper end of the piston rod, the opposite end of the arm being slidably connected with the said handle leg.

3. In a structure as defined in claim 2, and means for controlling the oil flow through the oil delivery spout, including an operating lever extended adjacent the operating arm of the air Dump- S Q EWING.
